Asus P5B mystery

[HardWired]

I know there is an official p5b thread here but it hasn't been visited in a couple of months by anyone so I was hoping someone might catch this one.

Problem: I've updated to the latest bios (1803) and now it seems like cpu throttling is on by default. Cpu-id will show the multiplier jump between 8 and 6. When not pushing the cpu it looks like its throttling down to 6x and pushing up to the 8x multiplier (on-the-fly) when needing more processing power.

I'm not seeing a way to shut this off in the new 1803 bios and I'm not able to flash back to a previous bios (yes I've tried in dos and using the native Asus EZ Flash app found in the bios).

If no one knows an answer to this can you point me to a forum/website that may be of more help.

Thx!

Wow! I've been working on this on and off all day and in the 15 min since I posted this, I finally hit a google link that helped. I was able to find a version of Asus Update that supports backwards flashing on (I would assume) all Asus mobos.

I'm back to the bios version I was at and overclocking like a motherflocker.

Is there in the BIOS an option in the JumperFree menu called SpeedStep?
Try to disable it, so is the C1E option.
I think this will solve the problem.
Actually it is not a problem, it is a function to save power and let the cpu runs cooler while it is idle.

Yes, Speedstep is in the earlier bios files but was missing in the new one (1803) and Asus (even with their dos flasher) wouldn't allow for backwards flashing/downgrading.

But I've since found and older version of their Win flasher that does allow for downgrading and I'm back to an older bios that was working great. Don't know why I flashed anyway. New isn't always better when it come to the bios.

And I understand the concept behind SpeedStep, but the new bios wouldn't even allow me to get to past 2.8 Ghz, so back I went.

I'm rock solid again at 3.4 Ghz with an E6400 (2.13Ghz) with stock cooling. That's one helluva o'c in anybodys book.
